Description
Goodman B1497204 Energy Cut-off Device Overview
The Goodman B1497204 is an OEM energy cut-off device designed to protect heating and HVAC equipment from dangerous overtemperature conditions. Rated at 140°C (284°F), this thermal safety device interrupts the electrical circuit when temperatures exceed the rated threshold, preventing equipment damage, component failure, and potential fire hazards.
How It Works
The energy cut-off device functions as a one-time thermal fuse or high-limit safety switch. When the surrounding temperature reaches the 140°C trip point, the device permanently opens the circuit, cutting power to the heating element or system. This irreversible action signals that a fault condition exists and that the root cause must be identified and corrected before replacing the device and restoring operation.
Key Features
- OEM Goodman replacement part — ensures proper fit and function
- 140°C (284°F) temperature rating for reliable overtemperature protection
- Designed to interrupt electrical circuits upon reaching the rated cut-off temperature
- Helps prevent equipment damage, component burnout, and fire hazards
- Direct replacement for compatible Goodman and Amana heating systems
- Compact design for straightforward installation in original mounting location
Application
- Goodman and Amana gas furnaces and heating equipment
- Residential and light-commercial HVAC systems requiring thermal overtemperature protection
- Replacement of failed or tripped energy cut-off devices during service calls
Important Service Note
Because this is a one-time thermal cut-off device, it cannot be reset after activation. A tripped device indicates an underlying overtemperature condition — always diagnose and correct the root cause (such as restricted airflow, failed blower motor, or blocked heat exchanger) before installing a replacement unit.
